' 3 Claims.

This invention relates to relatively large heavy doors used in garagesand the like where the space is restricted and where ease of operationis a primary consideration.

The primary object of the present invention is to provide an improvedmounting or suspension means for doors of the above kind, such mountingor suspension means being extremely simple and durable in constructionand comprising a small number of simple parts capable of being cheaplymanufactured and readily installed;

Another object of the present invention is to provide a door mounting orsuspension means of the above kind which is efficient in use andotherwise adapted to meet with the requirements for a successfulcommercial use.

Other objects and advantages of our invention will become apparent fromthe following description, when considered in connection with thaccompanying drawings. 7

In the drawings:

Figure 1 is a fragmentary vertical sectional view of the front portionof a garage or similar building having a door equipped with a mountingor suspension means constructed in accordance with the presentinvention.

Figure 2 is a horizontal section on line 22 of Figure 1.

Figure 3 is an enlarged fragmentary vertical section on line 3-3 ofFigure 1.

Figure 4 is a view similar to Figure 3 on line l4 of Figure 1; and. v

Figure 5 is an enlarged fragmentary detailed view partly in sideelevation and partly in section, showing details of the constructionillustrated in Figures 3 and 4, parts being broken away.

Referring in detail tothe drawings, 5 indicates a garage or likebuilding having side walls 6 and provided with a front door opening 1. v

Secured to the inner faces of the side walls 6 at opposite sides of thedoorway I. preferably horizontally so as to extend rearwardly from thefront of the building, are flat supporting boards or bars 8. Carried byeach supporting bar 8 is a hinge bracket including a base plate 9securely fastened as at l0 flatly against and to the associated bar 8and provided with an inwardly projecting rigid journal pin orstud Ii.

Rigidly attached to and extending inwardly from each side of the ,doorl2 are arms comprising a pair of T-iron members i3 which are attached attheir forward ends to the door i2 in vertically spaced relation as shownin Figure 1, and which converge rearwardly where they terminate inadjacent but spaced pazailel inner end portions l3a. As shown, anglebars 54 are preferably fastened along the vertical edges of the door i2,and the forward ends of the arm members l3 are rigidly attached to theinwardly ex- 8 tending flanges of these bars M as at i5. Also, theT-iron members l3 are disposed with their cross flanges adjacent andwith their intermediate flanges projecting away from each other.

The inner parallel end portions l3a of the 10 arm. members l3 aresecurely clamped between elongated hinge plates l6 and i1 having centralopenings IQ for reception of the journal pin or stud II. The plates l6and I1 are provided along their longitudinal edges with lateral flanges20 15 and 2| behind which the cross flanges of the arm members l3 areengaged so that their inner ends Ila are securely held againstspreading, and the plates i6 and il are also provided on thelrinnerfaces adjacent the inner sides'of the flanges 20 20 and 2! withroughened portions as at 22 engaging the edges of the cross flanges ofarm members I3 so that longitudinal displacement of the inner endportions Hit of said arm members I3 relative to the hinge plates i6 andI1 is effectively pre- 25 vented when said hinge plates are firmlyclamped together. The hinge plates i6 and ii are firmly clamped togetherby means of transverse clamping bolts 23 extending through reinforcedapertured ends of the hinge plate i1 and threaded 30 into reinforcedapertured ends of the hinge plate i6 as shown clearly in Figure 3. Theends'of these plates i6 and ii are preferably reinforced by providingthem on their inner faces with bosses 24 surrounding their end openingswhich 35 receive the bolt 23.

It will be readily seen that, by means of the construction described,the door i2 is mounted for vertical swinging movement about the axes ofjournal pins or studs Ii for swinging from the (0 vertical operativeposition shown by full lines in Figure 1 to the horizontal open positionshown by dotted lines in Figure 1, or vice versa. When open, the dooroccupies practically no space ex- A teriorly of the building, and doesnot move a 45 material distance forwardly of the door opening when beingopened or closed. The door may be easily opened by a lifting movementand easily lowered to close the same, said-door being counterbalanced bysuitable means such as a heliso cal tension spring 25 connected at oneend to the upper arm member l3 at each side of the door and connected atits other end to a suitable bracket 26 mounted in the buildingrearwardly of and above the point where each journal pin Ii is located.When open, the door is completely out of the way with its normally lowerend abutting the lintel 21 at the top of the door opening, theupwardswinging movement of the door 'being thereby limited to thedesired substantially horizontal overhead position. Any suitable meansmay be provided for retaining the hinge plates l6 and Il upon theassociated journal pin or stud i I, such as a cotter pin 28 placed in atransverse opening provided in the outer end oi said journal pin or studl i.

It will be seen that the present mounting is such as to eflectivelycarry out thestated objects of the invention, and it will be apparentthat the specific construction illustrated and described is susceptibleof changes and modifications such as fairly fall within the spirit andscope of the invention as claimed.

What we claim as new is:

1. In a hinge mounting for a counterbalanced door, a bracket adapted tobe fixed at one side of and inwardly oi the door opening and having alaterally projecting horizontal journal stud, arms adapted to be rigidlysecured to and to project inwardly from a side of the door andcomprising a pair of bars having adjacent spaced parallel inner endportions and outwardly diverging outer end portions, and a pair of hingeplates bolted together against opposite sides of said inner end portionsof said bars, said hinge plates having alined openings pivotallyreceiving the journal stud of said bracket.

2. In a hinge mounting for a counterbalanced door, a bracket adapted tobe flxed at one side of and inwardly of the door opening and having alaterally projecting horizontal journal stud, arms adapted to be rigidlysecured to and to project inwardly from a side of the door andcomprising a pair 0! bars having adjacent spaced parallel inner endportions and outwardly diverging outer end portions, and a pair of hingeplates bolted together against opposite sides of said inner end portionsof said bars, said hinge plates having alined openings pivotallyreceiving the journal stud of said bracket, said bars being oi T-ironform and arranged with their intermediate flanges projecting away fromeach other, said hinge plates having side flanges projecting inwardlytoward each other, the cross flanges of said bars being engaged behindsaid side flanges of the hinge plates.

3. In a hinge mounting for a counterbalanced door, a bracket adapted tobe fixed at one side of and inwardly of the door opening and having alaterally projecting horizontal journal stud, arms adapted to be rigidlysecured to and to project inwardly from a side 0! the door andcomprising a pair of bars having adjacent spaced parallel inner endportions and outwardly diverging outer end portions, and a pair oi hingeplates bolted together against opposite sides of said inner end portionsof said bars, said hinge plates having alined openings pivotallyreceiving the journal stud of said bracket, said bars being or T-ironform and arranged with their intermediate flanges projecting away fromeach other, said hinge plates having side flanges projecting inwardlytoward each other, the cross flanges 01 said bars being engaged behindsaid side flanges oi the hinge plates, said hinge plates being furtherformed with straight parallel roughened portions behind said sideflanges thereof engaged by theedges of said cross flanges oi the bars.
